Receiving-end buffer overflow probability guarantee based multi-path transmission packet scheduling method

Abstract

The invention discloses a receiving-end constrained buffer overflow probability guarantee based multi-path transmission packet distributing method. The method comprises the following implementation steps of estimating random distribution parameters of path delay by utilizing a sending end A according to real-time independent path delay information; calculating and solving a sending interval ratio R of the path according to receiving-end buffer overflow probability index requirements P of users; and dynamically adjusting the sending interval of the path and the sending sequence of packets according to a given packet distributing method by utilizing the sending end A so as to reduce the number of out-of-order packets as far as possible and guarantee that the receiving-end constrained buffer is incapable of overflowing. The method disclosed by the invention has the advantages that the receiving-end buffer packet overflow phenomenon can be prevented as far as possible by utilizing the index probability needing to be achieved by users; the receiving-end packet discarding problem caused by disorder is reduced; the upward submission continuity of business data is guaranteed; the throughput of network is increased; and the user experience is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a packet allocation method for multi-path transmission based on the guarantee of limited buffer overflow probability at the receiving end. Background technique [0002] With the diversified development of access technologies and the reduction of equipment costs, users' terminal equipment is gradually equipped with multiple network interfaces. Most of the current notebook computers, smart phones and other mobile terminals have two or more network interfaces. . On the other hand, more and more users tend to download some media services from the network, such as multimedia services such as movies and music. With the increase in the number of users and business types, and the high bandwidth requirements of multimedia services, a single network cannot provide sufficient bandwidth resources to meet user needs. Therefore, multi-path parallel transmission based on multiple acces...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies of the above-mentioned existing methods, and propose a packet allocation method for multi-path transmission based on the guarantee of the limited buffer overflow probability at the receiving end, to solve the problem of out-of-order packets in multi-path parallel transmission, and ensure the reception as much as possible. The end buffer does not overflow, so that the business data of the sending end user can be continuously submitted to the receiving end
